Just as a starter it looks like there are less connections in the adapter leads than there are in the Rover loom.
I think you're missing the steering wheel controls - which isn't a big issue in itself but it makes me wonder if there are other connections missing.
Do you have the RAVE wiring diagrams? You might have to go back to basics and follow through each wire from loom to unit. If you don't I'm sure we can give you a run down of what wires/numbers do what.
Or maybe it's something simple such as a blown fuse?
Good Luck.

PS Which passenger fuse box have you got? The "original" one with full sized fuses or the "new" one with mini fuses? AFAIK the wiring looms are different.
The original looks like this - it might not have the same relays etc. (RL1/RL2 etc.) depending on exactly which model/engine ZT-T you have. And the cables in the top right hand corner are my additions for an auxiliary socket.
